refactor: convert project to typescript (#47)

* refactor: convert project to typescript

* fix: image as last argument of docker run

* ci: remove example as the build can act as example

* fix: set tokenEnv to RENOVATE_TOKEN

* fix: add trailing single quite to Docker --env arguments

* fix: mount volume with config file to Docker container

* chore: remove Prettier trailingComma on all

This puts it back at the default, which is es5 style.

* fix: correct package main to dist/indes.js

* fix: use @actions/exec to execute docker child process

* fix: use async/await for exec
